BARREL-SMOKING OVEN.

Be it known that I, FRANCisznK STAN- nowsKi, subject of the Czar ofRussia, re-

c siding at Baltimore, in the county of Balti- .more City and State ofMaryland, have 1nvented certain new and useful Improvements inBarrel-Smoking Ovens, of which the. following is a specification.

This invention relates to the art of coopering and has special referenceto a barrel smoking oven.

As usually practised in cooper shops the l barrels, after the Staves andheads are as.-

sembled and hooped, are subject to abath of hot smoke for the purpose ofclosing the wood pores after thoroughly drying the barrels. i

This operation is performed in the open shop or in ovens in theshop withthe result that the smoke spreads through the entire shopthus workinggreat inconvenience to the workmen and detriment to their health.Moreover, this' method can not insure a proper bathing in ydense smokeowing to the freedom with which the smoke will escape from the vicinityof the barrels.

One important object of the invention is to provide an improved form ofsmoking oven so proportioned and constructed as to effect the bathing ofthe barrels in a body ofdense smoke without the smoke finding its wayinto the shop, the apparatus beingnot produce a smoke of requisitedensity' owing to the fact that too great a quantity of "oxygen (fromthe air) is permitted tov combine with the carbonaceous elements of thefuel employed and the proper imperfect combustion is not effected.

A second important object of the invention isl to provide an improvedconstruction of oven so proportioned and arranged as to produce suchimperfect combustion as will result in the production of a body of densesmoke in the vicinity 'of the barrels to be smoked.

A third important object of the invention is to provide such means ofintroducing the air. which is necessary forsuchcombustion, to the ovenin such manner as to have very little effect in causing movement of thesmoke away from the vicinity of the barrels being treated.v

Patented June 12, 1917. serial No. 136,318.

Vith the above and other objects in view, as will be hereinafterapparent the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specilically claimed.

In the accompanying drawing, like characters of reference indicate likeparts inthe several views, and

Figure 1 is a front View of the oven.

Fig. 2 is a vertical median section thereof.

`Fig. 3 is a section on the line 3-3 of Fig. 2.

' Fig. Fia 2- Y .Fig 5 is a section on the line 5-5 of Fig. 2.

In carrying out this invention I have 4i is a section on the line 1 -4of found that there are certain definite relationships existing betweenthe cross sectional areas of different parts of the device which 'mustbe closely adhered*v to v,in order to 'progreat motion in the body ofsmoke produced by the inflowing air.

To this end I provide a smoke chamber 10 having a front wall 11 providedwith an access opening 12 which is closed hermetically by doors 13 whenthe barrels B are being smoked. The bottom 14 of this chamlber forms arectangular hearth on which the fuel is placed, the barrels beingsupported on brick stools 15.

The rear wall 16 of this chamber preferably forms the outer wall of thebuilding and is provided With a flue opening from the outside as lat 17and extending vertically up to the top of the rear Wall the verticalportion being shown at 18. The top of the chamber starts level with theinner flue opening and extends upwardly and rearwardly at an angle of 45so that the brick courses may form a series of inverted steps 19 thetreads and risers of which are equal.

peculiar importance as otherwise too rapid an upward flou' of smoke willresult or, if the angle is made less` the damping effect will be toogreat and the fire will go out.

I have found this feature to be of tions this air is just suflicient'toFrom the top extends upward a smoke flue 20 having its back wallcontinuous with' the back wall of the flue 18 and of a cross sectionalarea equal to one-ninth the hearth and efficient device of the. kinddescribed and for the purpose specified,

is claimed as new, is l 1'. A barrel smoking oven Having thus describedthe invention, what chamber having a hearth, 'hermetically closing doorsat the front of the chamber, an aii` inlet flue opening into the'upperpart of the chamber, and a smokel flue extending upward from the too ofsaid chamber and having a cross sectional area not greater` thanone-ninth the door area of the cham- Icomprising a ber, the air inletHue having a cross sec'- tional area not greater `than one-sixth thecross sectional area of the smoke flue.

2. A barrel smoking oven comprisinga chamber having a Hoor constitutinga hearth, doors hermetically closing' the front wardfrom the top of thechamber andhav- 1 ing a. cross sectional area not greaterthan one-ninthlthe floor area-of the hearth, the

top. of said chamber being inclined from the' front to "the rear at anangleof not more than 45 to the horizontal, said top being angularly'corrugated transversely of the chamber,..the chamber having a back wallprovided withv an air inlet flue .opening from the outside near 'thebottom of the wall and' extending vertically upward in v the wall toopen on a' levelv withthe lower edge of thechamber'top, said air inletiue" having a cross sectional .area l,not vgreater than one-sixththecro'ss sectional area voi the smoke Hue. v
